The design of electro-hydraulic control unit switching

2a - The hydraulic unit 11 - 13-pin connector Y3 / 6 - Electric control unit switchover Y3 / 6b1 - ATF temperature sensor Y3 / 6n2 - 2 RPM Sensor Y3 / 6n3 - Sensor 3 revolutions Y3 / 6s3 - Contact immobilizer Y3 / 6y1 - e / m control valve modulation pressure	Y3 / 6y2 - e / m pressure control valve switching Y3 / 6y3 - e / m switching control valve 1-2 and 4-5 Y3 / 6y4 - e / m control valve switching 3-4 Y3 / 6y5 - e / m control valve switching 2-3 Y3 / 6y6 - e / m Valve PWM converter lock

The design of the selector module (without serial ranging - models of early years of release)

67 - Lock the selector lever position 68 - Mechanical disconnector switch D-4 69 - lock mechanism switching R / P 72 - Position indicator lever	S16 / 10 - position sensor AT S16 / 10s1 - sensor switch lights reverse Y66 / 1 - e / m actuator lock switching R / P

1 - 3 RPM sensor (Y3 / 6n3) 2 - E / magnetic modulating pressure control valve (Y3 / 6y1) 3 - 2 RPM sensor (Y3 / 6n2) 4 - Input temperature sensor (Y3 / 6b1) and contact blocking of a starter (Y3 / 6s1) 5 - 6 - Power supply e / solenoid valves 7 - Power supply sensor	8 - E / solenoid valve gear 2-3 (Y3 / 6y5) 9 - E / solenoid valve gear 3-4 (Y3 / 6y4) 10 - E / pressure control solenoid valve switch (Y3 / 6y2) 11 - E / solenoid valve (locking of the rotation) (Y3 / 6y6) 12 - Sensor housing 13 - E / shift solenoid valve 1-2 / 4-5 (Y3 / 6y3)

TCM detects the current operating parameters of the vehicle and controls the sequential shift transmission, on the basis of ease of switching and driving parameters.

Activating the solenoid valve switching is carried out by command of the control unit TCM. The desired pressure value is calculated based on incoming data and correction adjustment required transmitted torque.
